[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] The following combination Figure 1 An air inlet assembly according to an embodiment of the present invention is described.

[0023] The air inlet assembly of the present utility model embodiment includes an inner unit body and a finger guard grille 3. The inner unit body is formed with an air supply channel 2 and an air inlet hole 121 that are connected. The air inlet hole 121 is located below the air supply channel 2. The inner wall surface of the air supply channel 2 is provided with a mounting position 111 for mounting electrical components. The finger guard grille 3 is installed in the air inlet hole 121. The finger guard grille 3 includes a plurality of first partition ribs 31 arranged at intervals along a first direction. The first direction is parallel to the height direction of the inner unit body ( Figure 1 The distance between any two adjacent first partition ribs 31 is a, and the distance between the upper surface of the finger guard grille 3 and the lowest point of the mounting position 111 in the height direction of the inner machine body is b, wherein 8mm≤a≤18mm, and b≥70mm.

[0024] According to the air intake assembly of the embodiment of the present invention, by setting the distance between any two adjacent first partition ribs 31 to be greater than or equal to 8 mm, the first partition ribs 31 are effectively prevented from being arranged too densely and occupying too large an area of ​​the air inlet hole 121, thereby effectively ensuring the air intake area at the air inlet hole 121. By setting the distance between any two adjacent first partition ribs 31 to be less than or equal to 18 mm, the distance between the upper surface of the finger guard grille 3 and the lowest point of the mounting position 111 in the height direction of the inner unit body is greater than or equal to 70 mm, ensuring that only fingers can pass through the finger guard grille 3 to enter the air supply duct 2, and fingers will not come into contact with electrical components installed in the mounting position 111, thereby effectively reducing the risk of electric shock to personnel and effectively improving the safety of the air conditioner.

[0025] It should be noted that the distance between any two adjacent first partition ribs 31 can be 8 mm, 12 mm, 15 mm and 18 mm, and the distance between the upper surface of the finger guard grille 3 and the lowest point of the mounting position 111 in the height direction of the inner machine body can be 70 mm, 75 mm and 80 mm.

[0026] In some embodiments, as Figure 1As shown, the maximum width of the first partitioning rib 31 is c, where 2mm≤c≤5mm.

[0027] This design avoids the first partitioning rib 31 having a too small maximum width and thus having poor strength and poor protection, and avoids the first partitioning rib 31 having a too large maximum width and thus blocking too much of the area of the air inlet hole 121, which affects the air inlet area at the air inlet hole 121 and makes the air conditioner have a higher air supply efficiency.

[0028] Specifically, the maximum width of the first partitioning rib 31 can be 2mm, 4mm, and 5mm.

[0029] In some embodiments, as shown in FIG. 1, the first partitioning rib 31 has a maximum width of 2mm. Figure 1 As shown, the width of the first partitioning rib 31 gradually increases from bottom to top.

[0030] With the maximum width of the first partitioning rib 31 being fixed, this arrangement further reduces the projected area of the first partitioning rib 31 in the projection plane perpendicular to the up-down direction, ensures the air inlet area at the air inlet hole 121, and greatly reduces the air resistance when the airflow passes through the first partitioning rib 31 when the airflow passes through the finger guard grid 3, which makes the airflow form a vortex at the first partitioning rib 31 less efficient and makes the air conditioner have a higher air supply efficiency.

[0031] Specifically, the bottom surface of the first partitioning rib 31 is a downwardly concave arc surface, and the plurality of first partitioning ribs 31 are arranged at equal intervals in the front-rear direction.

[0032] In some embodiments, as shown in FIG. 1, the first partitioning rib 31 has a maximum width of 2mm. Figure 1 By setting the height of the first partitioning rib 31 to be greater than or equal to 2mm, the first partitioning rib 31 has sufficient structural strength and ensures its protection reliability, and by setting the height of the first partitioning rib 31 to be less than or equal to 8mm, the upper surface of the first partitioning rib 31 is effectively prevented from being too close to the lowest point of the water pan 5, which would cause the airflow to be directly guided by the finger guard grid 3 to the bottom surface of the water pan 5 and thus increase the air inlet resistance.

[0034] Specifically, the height of the first partitioning rib 31 can be 2mm, 5mm, and 8mm.

[0035] In some embodiments, as shown in FIG. 1, the first partitioning rib 31 has a maximum width of 2mm. Figure 1 The air inlet grid 4 is arranged in the air inlet hole 121, and the air inlet grid 4 and the finger guard grid 3 are arranged along the height direction of the indoor unit body.

[0036] The air inlet grid 4 improves the structural strength of the indoor unit body at the air inlet hole 121, protects the evaporator, the water pan 5, and the electrical components in the air supply passage 2, and improves the appearance of the air inlet assembly at the air inlet hole 121.​

[0037] In some embodiments, as shown in FIG. 1, the first direction is consistent with the width direction of the inner unit body, and the air inlet grille 4 includes a plurality of second partitioning ribs 41 arranged at intervals along the width direction of the inner unit body, and the distance between any two adjacent second partitioning ribs 41 is greater than the distance between any two adjacent first partitioning ribs 31. Figure 1 That is, the air inlet grille 4 mainly plays a protective and aesthetic role, and will not excessively block the air inlet hole 121 to affect the air inlet area at the air inlet hole 121. At the same time, the arrangement direction of the plurality of first partitioning ribs 31 is consistent with the arrangement direction of the plurality of second partitioning ribs 41, so that part of the first partitioning ribs 31 and the second partitioning ribs 41 partially overlap in the vertical direction, effectively reducing the total projection area of the two in the projection plane perpendicular to the vertical direction, further improving the air inlet area at the air inlet hole 121, and the air supply efficiency of the air conditioner is higher.

[0038]

[0039] Specifically, the plurality of second partitioning ribs 41 are arranged at equal intervals along the front-rear direction, and the air inlet grille 4 can further include a horizontal rib extending along the left-right direction of the air conditioner, and the horizontal rib connects adjacent two second partitioning ribs 41 to further ensure the structural strength of the air inlet grille 4. At the same time, the finger guard grille 3 also includes a horizontal rib extending along the left-right direction of the air conditioner, and the horizontal rib connects adjacent two first horizontal ribs to further ensure the structural strength of the finger guard grille 3.

[0040] In some embodiments, the air inlet grille 4 is located below the finger guard grille 3, and the air inlet grille 4 is detachably connected with the inner unit body.

[0041] By detachably connecting the air inlet grille 4 with the inner unit body, the manufacturing cost of the air inlet grille 4 is effectively reduced, and it is also convenient to detach the air inlet grille 4 to realize cleaning of the air inlet grille 4 and the inner finger guard grille 3.

[0042] Specifically, the air inlet grille 4 is clamped in the air inlet hole 121, or the air inlet grille 4 is fastened in the air inlet hole 121 by a threaded member.

[0043] In some embodiments, the inner unit body includes a base 6 and a middle frame 1, the base 6 and the middle frame 1 are connected and surround to form the air supply channel 2, the middle frame 1 includes a front panel 11 and a bottom plate 12 connected with each other, the inner wall surface of the base 6 and / or the inner wall surface of the front panel 11 is provided with a mounting site 111, the bottom plate 12 is provided with the air inlet hole 121, and the front panel 11, the bottom plate 12 and the first partitioning rib 31 are integrally formed.

[0044] By integrally forming the middle frame 1 and the finger guard grille 3, the number of parts of the air conditioner is effectively reduced, the assembly efficiency of the air conditioner is improved, and the connection strength of the bottom plate 12 and the finger guard grille 3 is also effectively improved.

[0045] ​In some embodiments, the inner wall surface of the front panel 11 is provided with a mounting position 111, and the distance between the upper surface of the finger guard grid 3 and the lowest point of the mounting position 111 provided at the front panel 11 in the height direction of the indoor unit body is b.

[0046] The mounting position on the front panel 11 is used for mounting the display panel and the stepping motor, and the height of the display panel and the stepping motor is lower than the height of the electrical devices on the base 6. On the basis that the distance between the display panel and the stepping motor and the upper surface of the shroud grid 4 is greater than or equal to 70 mm, the risk that the staff member passes through the air supply channel 2 and touches the electrical devices in the air supply channel 2 by the finger guard grid 4 is basically avoided, and the use safety of the air conditioner is higher.

[0047] In some embodiments, the air supply channel 2 is provided with a water collecting tray 5, and the distance between the lowest point of the outer wall surface of the water collecting tray 5 and the upper surface of the first partition rib 31 in the height direction of the indoor unit body is h, wherein h is greater than or equal to 8 mm.

[0048] The arrangement avoids that the water collecting tray 5 is too close to the finger guard grid 3 in the up-down direction and blocks the air inlet hole 121. The air inlet hole 121 can have a larger space to flow after passing through the finger guard grid 3 so as to bypass the water collecting tray 5, the air flow resistance of the air flow passing through the water collecting tray 5 is smaller, and the air supply efficiency of the air conditioner is higher.

[0049] Specifically, the distance between the lowest point of the outer wall surface of the water collecting tray 5 and the upper surface of the first partition rib 31 in the height direction of the indoor unit body can be 8 mm, 10 mm and 12 mm.

[0050] It should be noted that the air inlet assembly further comprises a filter screen, the filter screen is detachably arranged in the air inlet hole 121, and the filter screen is located below the air inlet grid 4. The filter screen is used for preventing external dust from entering the air supply channel 2, effectively ensuring that each component in the air supply channel 2 is clean and hygienic, and greatly prolonging the cleaning period of the air conditioner.
